SERVICE-BOX FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 370,433. dated September 27, 1887.

Application filed February 3, 1887. Serial No. 226,422. (No model.)

To all whom it may concern:

Be it known that l, DARIUS WELLINGTON, a citizen of the United States, and a resident of Boston, in the county of 'Sufiolk and State of Massachusetts, have invented new and useful Improvements in Service-Boxes for Water- Glosets, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in service-boxes for water-closets, and it is carried out as follows, reference being had to the accompanying drawings, wherein Figure 1 represents a plan view of the invention, and Fig. 2 represents a longitudinal section of it, showing the valvein the servicebox as open and the bottom of the service-box closed. Fig. 3 represents a detail sectional view showing the valve closed and the bottom of the service-box open to allow the water from the bottom of the tank to enter it when the cover of the water-closet is raised.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

c is the water-tank, as usual, which is kept constantly filled, or nearly so, with water by means of any of the well-known automatic supply devices, such devices being, however, not shown in the drawings.

To the bottom of the tank a,I secure a metal plate, I), provided with a discharge-pipe, b, that projects downward through a perforation in the bottom of the tank a, as shown in Figs. 1 and 2. I prefer to interpose a sheet of rubber or other packing, 0, between the plate b and the bottom of the tank a, as shown. Ialso prefer to secure to the upper side of the plate I) a sheet of suitable packing, d, to effect a tight connection between said plate and the under side of the service-box e when the latter is in its normal closed position. (Shownin Figs. 1 and 2.)

To the plate I) are secured or cast in one piece the upwardly-projecting ears I) b, to which is secured the fulcrum-pin b on which the service-box e is pivoted, having for this purpose a lip, e, embracing the fulcrum-pin b such lip being rounded on its under side, so as to roll on the plate b (or its packing (1) while in the act of being opened or closed. By

this arrangement the whole weight of the service-box e is brought to bear on the packing d, to effect a tight connection between such parts when the service-box'is closed, all strain on the fulcrum-pin b is relieved, and the service-box 6 can be detached from the fulcrumpin 1) simply by swinging it downward into the tank a, and as easily put in place therein without disconnecting the bolt b or otherparts of the device. The service-box e is open from top to bottom, as shown, and has on its inside near its lower end a projection, e, for actuating theflush-valve f, as will be hereinafter more fully described.

To the upper end of the service-box e is attached one end of a cord or chain, g, that is carried over or between pulleys h h, located in a bearing secured to the top of tank a, as shown in Figs. 1 and 2, the other end of said cord or chain being secured to an arm or projection, i, on the cover I, hinged to the watercloset box I, as shown in said Figs. 1 and 2.

B is the flush-pipe leading from the lower end of the discharge-pipeb to the water-closet bowl, as usual. Theflush-valvefis weighted, so as to rest closed on the upper end of the discharge-pipe b, as shown in Fig. 3, when the cover of the water-closet is raised. I make through the side of the upwardly-projecting part of the discharge-pipe b a small perforation, b, (shown in Figs. 2 and 3,) to allow a small quantity of water to pass to the pipeB and water-closet when the latter is in use, and thus keep up a small stream flowing to the bowl of the closet when in use. The same ob ject may be accomplished by means of the thumb-screw f, screwed through a screwthreaded perforation in a side projection on the valve f, the lower end of said screw being so adjusted as to bear against the plate Z) or its packing just sufficiently to keep the valve f alittle above its seat when the closet is used. The valve f has on its upper side a groove,

f, embracing the fulcrum-pin 11*", secured to 3 sion f on said valve f, as shown in Figs. 1

and 2, causing such water remaining in the service-box e to pass out through the pipes 12 and B, and after all the water in the servicebox 6 has flowed out through said pipes all communication from the tank a to the watercloset is cut off. When the cover I is raised 15 preparatory to using the closet, the servicebox 6 is tipped on its fulcrum b, by the influence of .the cord or chain 9, to the position shown in Fig. 3, by which the projection ein the service-box is relieved from the lip f 'on the weighted valve f, causing the latter to antomatically close the upper end (or partially so) of the discharge-pipe b, and allowing the water in the tank a to pass up through the now open bottom of the service-box 6, so as to make the water level in the tank a and service-box. As long as the cover I is raised, a small stream of water passes from tank a through the small perforation b (or the partially-open valve f) to the pipe B and the bowl of the closet. As

0 soon as the coverI is closed, the service-box e returns by its own weight to the position shown in Figs. 1 and 2, by which its lower end is closed, as above described, and the valve f automatically opened by the influence of the projcction e on the valve-lip f thus allowing all the water contained in the service-box e to pass by the open valve f and out through the pipes 12 B to the bowl of the water-closet, and so on. The service-box e is sufficiently heavy to cause the cover I to be automatically closed as soon as a person leaves the seat of the closet.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent, and claim 1. In combination with the tank a, the service-box e, open from end to end and pivoted in its lower end to the stationary fulcrum-pin b and the weighted valve f, having lip f actuated by the projection 0 within the servicebox e, as and for the purpose set forth.

2. The tank a and the open-ended servicebox 6, pivoted to its bottom, as described, and having projection e, in combination with the valve f, its lip f the discharge-pipe b, and flush-pipe B, leading to the water-closet bowl, and the chain or cord 9, leading from the service-box e to the cover I of the water-closet, as and for the purpose set forth.

3. The open-ended service-box e, pivoted to the tank-a, and having the projection 6, combined with the pivoted valve fand its lip f and the discharge-pipeb, with its side perforation, b, as and for the purpose set forth.

4. The open-ended service-box e, pivoted to the tank a, and having the projection 6, combined with the pivoted valve f and its lip f", and regulating-screw f, as and for the purpose set forth.

5. The plate b,'having the discharge-pipe I) and fulcra b b as described, in combination with the open-ended service-box e, pivoted to the fulcrum b and having valve-operatin g projection e, and the valve f, pivoted to the fulcrum b and having lip or projection f, as and for the purpose set forth.

6. The tank a, combined with the openended service-box e and valve f, both pivoted at or near the bottom of said tank and having the respective projections e and to automatically open and close the valve f by the rocking motion of the service-box, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 25th day of January, A. D. 1887.

DARIUS WELLINGTON.
